Description
Technical Field
[0001] The invention relates to the field of flexible printed circuit board (FPC) manufacturing equipment, in particular to a flexible FPC nickel sheet and gold finger electrical introduction test module and a test machine thereof. Background Art
[0002] Flexible circuit boards, also known as "FPC soft boards", are printed circuit boards made of flexible insulating substrates. FPC can provide excellent electrical performance, meet the needs of smaller and higher density installation designs, and also help reduce assembly processes and enhance reliability. Flexible circuit boards FPC soft boards can be bent, wound, and folded freely, and can withstand millions of dynamic bends without damaging the wires. They can be arranged arbitrarily according to spatial layout requirements, and can be moved and stretched arbitrarily in three-dimensional space, thereby achieving the integration of component assembly and wire connection; and can greatly reduce the size and weight of electronic products, which is suitable for the development of electronic products towards high density, miniaturization, and high reliability.
[0003] The manufacturing process of flexible FPC involves a testing process. After it is electrically connected to the test circuit, the test circuit is used to simulate and test various electrical performance indicators of the flexible FPC. In the specific test process, it is generally necessary to use multiple probes to independently contact the multiple metal nickel sheets on the side of the flexible FPC belt body, and at the same time, it is necessary to use multiple probes to synchronously contact the multiple conductive contact sheets of the gold fingers at one end of the flexible FPC in order to connect the flexible FPC to the test circuit; based on this test process requirement, during the automated testing of the flexible FPC, it is necessary to simultaneously connect the multiple metal nickel sheets of the flexible FPC and the multiple conductive contact sheets of the gold fingers to the test circuit. Generally, a needle-shaped probe is used as the electrical contact medium. The technical difficulty in the contact process is that the contact position height is difficult to control, and the circuit cannot be turned on if the contact is not complete. If the contact is too much, the circuit will not turn on. If the probe is too far away, it will bend and deform. In addition, since multiple probes are required to contact the multiple contacts of the gold finger synchronously, high requirements are placed on the position accuracy and flatness of the probes and the gold finger. A slight position deviation will result in inaccurate contact, and deviation in flatness will also lead to height differences among the multiple probes. When the height of the conductive contact remains unchanged, the low-positioned probe will be excessively bent, and the high-positioned probe will not be able to contact the conductive contact. In view of this, it is necessary to design an electrical import test module that can simultaneously complete the synchronous access of multiple nickel sheets of the flexible FPC and the gold finger to the test circuit under the premise of solving the above-mentioned technical problems.

[0016] A testing machine for a flexible FPC nickel sheet and a gold finger electrical introduction testing module.
[0017] The beneficial effects of the present invention are: In view of the defects and shortcomings of the prior art, the present invention independently develops and designs a flexible FPC nickel sheet and gold finger electrical test module and a test machine thereof, which can simultaneously realize the electrical test conduction of multiple nickel sheets and gold fingers, and has conduction pre-pressure, guiding and extreme limiting functions, to ensure the position and flatness accuracy of the FPC belt body and the gold fingers before conduction, and to realize flexible contact of the probe, effectively reducing the bending deformation of the probe during the contact process and the damage to the surface of the nickel sheet or the conductive contact sheet.
[0018] The present invention belongs to a mechanism and automated equipment for testing the electrical parameters of a flexible FPC, and realizes connecting multiple nickel sheets and gold fingers of a flexible FPC to a test circuit at the same time to complete automatic testing of various electrical parameters after it is manufactured. Specifically, the present invention is arranged as a whole above a test platform of a test machine, and a horizontally arranged frame-shaped bracket is used as a support structure. The bracket is provided with multiple groups of test drive mechanisms for providing a driving force in a vertical direction to drive the test mechanism below it to rise and fall, so that the gold finger test head of the test mechanism and multiple groups of nickel sheet test heads contact downwardly multiple nickel sheets and gold fingers of a flexible FPC placed on the test platform to achieve electrical conduction.
[0019] The special feature is that the test drive mechanism of the present invention adopts a connection structure in which the first drive component and the second drive component are connected in series. By arranging the second drive component on the output end of the first drive component, the test descent stroke can be effectively improved, which can be adapted to test scenarios with higher test stroke heights, and the test descent height can be adjusted in real time during the actual test process according to different stroke heights; in addition, the use of two sets of drive component structures can effectively avoid the downtime problem caused by cylinder failure during the actual test process; in addition, based on the inverted structure of the test mechanism and the influence of its own weight, in order to control the test descent stroke with high precision, the self-weight cylinder arranged in the test drive mechanism of the present invention continuously provides an upward pulling force according to the self-weight of the test mechanism to offset its own weight.
[0020] The special feature is that, for the synchronous conduction test of multiple nickel sheets, the present invention uses a floating support plate that is floatingly connected to the bottom of the test box as a bearing plate, and arranges multiple groups of nickel sheet test heads at intervals at the bottom of the floating support plate, and uses the flexible connection of the floating support plate to realize adaptive adjustment of the multiple groups of nickel sheet test heads during the test. That is, in the process of multiple groups of nickel sheet test heads contacting the nickel sheet respectively, if there is inconsistent flatness, the first probe that first contacts the nickel sheet will transmit the reaction force of the nickel sheet to the floating support plate, so that the floating support plate can adaptively adjust its angle or height until the first probes of all nickel sheet test heads contact the nickel sheet to ensure the integrity of the test; in addition, this kind of floating flexible contact has a certain buffering force, which effectively reduces the bending deformation of the first probe due to excessive force; in addition, the test seat of the nickel sheet test head of the present invention is connected to the bottom of the floating support plate through an elastic connector, so that the first probe inserted in the test seat has a flexible buffering force during the contact with the nickel sheet, avoiding the bending deformation of the needle body caused by rigid contact. In addition, in the process of synchronously descending and contacting multiple nickel sheets, the multiple nickel sheet test heads of the present invention are guided and limited by the first guide rod to ensure the synchronization of the descent and the consistency of flatness; at the same time, the pre-pressing seat with a height difference setting is used to pre-press the FPC belt body during the descent process, so as to achieve pre-pressing before the first probe contacts the nickel sheet, effectively ensure the position stability of the FPC belt body, avoid position deviation and the like in the subsequent process of receiving the downward contact force of multiple first probes, and improve the position accuracy; in addition, because the first probe is a bendable needle-shaped structure, in the process of descending and contacting the nickel sheet, if the first probes at different positions are different due to excessive descent or due to the difference in flatness during the descent, the first probes may be bent and deformed due to the upward reaction force, and therefore, the height of the first probe is preset by the first limit limit column and the rigid contact between the first limit limit column and the test platform during descent, so as to limit the descent height of the first probe, effectively control the limit height of its descent, and avoid the bending and deformation of the first probe.
[0021] The special feature is that, in response to the test requirement that the gold finger needs to synchronously contact multiple conductive contact pieces, the gold finger test head of the present invention adopts a sleeve pressure assembly to be arranged below the probe assembly. The probe assembly is in rigid contact with the test box, and when subjected to a downward driving force, the sleeve pressure assembly is driven to descend to complete the synchronous contact and conduction of multiple conductive contact pieces. Specifically, the connecting piece and the first spring are used as the elastic connection structure of the support plate and the probe cover. The connecting piece is inserted into the probe cover from above, and its upper end is fixed to the support plate by a threaded connection, and is movably connected to the probe cover. The cap body inverted at its lower end supports the probe cover. This connection method allows the probe cover to have a certain spacing of free movement space in the vertical direction, and the first spring is used to connect the support plate and the probe cover as an elastic buffer structure. In the initial state, the second probe is located in the probe cover to play a protective role. When the gold finger test head is lowered as a whole, the bottom surface of the probe cover first contacts the gold finger. In the process of the second probe moving downward to contact the conductive contact piece of the gold finger, the gold finger is pre-pressed and fixed to ensure the stability of the gold finger position. The gold finger is precisely controlled and the surface flatness is improved, so that the subsequent multiple second probes can accurately contact the conductive contact piece and maintain a high degree of consistency during the contact process; in the process of the gold finger test head continuing to descend after pre-compression, the probe cover is subjected to an upward reaction force and moves upward close to the support plate, so that the probe seat drives the second probe to move downward relative to the probe cover until the second probe passes through the probe hole and contacts the conductive contact piece, and the gold finger is connected to the test circuit; at the same time, during the upward movement of the probe cover, the first spring is compressed, which can provide a buffer, so that the process of the second probe passing through the probe hole (that is, the process of contacting the conductive contact piece) is a flexible contact, and the elastic force of the first spring acts downward on the probe cover in the opposite direction, so that it continues to press the gold finger during the test process to maintain its position stability and flatness consistency; further, in the process of the second probe contacting the conductive contact piece, compared with the traditional suspended contact method, its outer edge uses the probe hole to guide and protect it, so that it only needs to expose its end to the probe hole to contact the conductive contact piece, which can effectively protect the second probe and greatly reduce the bending deformation caused by excessive force. Furthermore, based on the premise that the lower end of the second probe includes an inner metal layer and an outer coating layer, the probe hole of the probe cover is designed to be a first hole body and a second hole body structure from top to bottom, and the metal layer can extend through the second hole body to the bottom of the probe cover to contact the conductive contact piece during the descent of the second probe by utilizing the step blocking surface between the connection points, and the outer coating layer of the second probe is blocked by the step blocking surface. Through this structure, the descent height of the second probe can be accurately controlled to avoid excessive descent to cause bending and breakage or damage to the conductive contact piece.

The second limit limit column 389 is designed with a height difference from the second probe 385. During the descent of the second probe 385, it can be in rigid contact with the test platform, and is used to limit the descent height of the second probe 385 to avoid bending and deformation of the second probe due to the reaction force caused by excessive descent.
[0060] The sleeve pressing assembly includes a probe sleeve 386, a first spring 387, and a connecting piece 388, wherein the probe sleeve 386 is spaced below the support plate 383 and is movably connected to the support plate 388 through at least two connecting pieces 388; a downwardly protruding cavity is provided at the bottom of the probe sleeve 386, a movable groove C is provided inside the cavity, and the top of the movable groove C is open so as to cover the probe seat 384 from below; at least two probe holes D are provided in the movable groove C corresponding to at least two second probes 385 so as to allow the second probes 385 to pass through; the first spring 387 includes at least two, and at least two first springs 387 are connected to the support plate 383 and the probe sleeve 386 to provide a buffering force.

[0062] The connector 388 and the first spring 387 are used as the elastic connection structure between the support plate 383 and the probe cover 386. The connector 388 is inserted into the probe cover 386 from above, and its upper end is fixed on the support plate 383 by a threaded connection, and is movably connected with the probe cover 386. The cap body hanging upside down at its lower end supports the probe cover 386. This connection method allows the probe cover 386 to have a certain spacing of free movement space in the vertical direction. At the same time, the first spring 387 is used to connect the support plate 383 and the probe cover 386 as an elastic buffer structure; in the initial state, the second probe 385 is located in the probe cover 386 to play a protective role. When the gold finger test head 38 is lowered as a whole, the bottom surface of the probe cover 386 first contacts the gold finger 02. In the process of the second probe 385 moving downward to contact the conductive contact piece 03 of the gold finger 02, the gold finger 02 is pre-pressed and fixed to ensure that the gold finger 03 The position stability and surface flatness facilitate the subsequent multiple second probes 385 to accurately contact the conductive contact piece 03 and maintain high consistency during the contact process; when the gold finger test head 38 continues to descend after pre-compression, the probe cover 386 is subjected to an upward reaction force and moves upward close to the support plate 383, so that the probe seat 384 drives the second probe 385 to move downward relative to the probe cover 386 until the second probe 385 passes through the probe hole D and contacts the conductive contact piece 03, connecting the gold finger 02 to the test circuit; at the same time, during the upward movement of the probe cover 386, the first spring 387 is compressed and can provide a buffer, so that the process of the second probe 385 passing through the probe hole D (i.e., the process of contacting the conductive contact piece 03) is a flexible contact, and the elastic force of the first spring 387 acts in the reverse downward direction on the probe cover 386, so that it continues to press the gold finger 02 during the test process to maintain its position stability and flatness consistency.
[0063] In addition, based on the premise that the lower end of the second probe 385 includes an inner metal layer and an outer coating layer, the probe hole D of the probe cover 386 is designed to be a top-down structure of a first hole body D1 and a second hole body D2. By utilizing the step blocking surface between the connection between the two, during the descent of the second probe 385, its metal layer can extend through the second hole body D2 to the bottom of the probe cover 386 to contact the conductive contact piece 03, and the outer coating layer of the second probe 385 is blocked by the step blocking surface. Through this structure, the descent height of the second probe 385 can be accurately controlled to prevent it from bending and breaking due to excessive descent or damaging the conductive contact piece 03.

During the test, after the probe seat 386 contacts the surface of the gold finger 02 in advance, the probe seat 386 is subjected to the upward reaction force of the gold finger 02 during the continued descent, and moves upward, so that the third spring 3813 is compressed, and at the same time, the second probe 385 moves downward relatively, passes through the probe hole D to contact the conductive contact piece 03 of the gold finger 02, and realizes electrical conduction; at the same time, the elastic force of the third spring 3813 is used to press the probe cover 386 downward in the reverse direction, so that the probe cover 386 continuously presses down and fixes the gold finger 02, thereby ensuring the position accuracy and flatness stability of the gold finger 02 during the test.
